It's all over the counter here. No archery specific season. Non-resident licenses are pretty affordable compared to many states. Regulations can be found here:
https://www.agfc.com/en/hunting/turkey/To be honest, I'd plan on the trip being a visit for your friend first and an opportunity to possibly hunt as a secondary thing to do while here. Arkansas turkey is not only a very short season, but it hits late for their prime time for movement every year and it is always pretty spotty at best. All of the serious turkey hunters that I know from around here plan multiple out of state hunts and just do Arkansas' season in between as an auxiliary hunt to be honest. I hunt them every year but only because it's in a season that isn't competing with other game animals. Arkansas has much better hunting opportunities for ducks, deer, feral pigs, black bear, and small game (squirrel, rabbits, etc). Alligator, turkey, elk, and upland birds diversify the field but really aren't destination hunting opportunities for this area in my opinion.
